alkylation of a methyl group, on di‐ and trisubstituted ureas, with terminal alkenes by C(sp3)−H bond activation proceeded in the presence of a hydroxoiridium/bisphosphine catalyst to give high yields of the corresponding addition products. The hydroxoiridium/bisphosphine complex generates an amidoiridium intermediate by reaction with ureas having an N−H bond.
在羟基铱/双膦催化剂的存在下,通过C(sp 3)-H键活化二末端和三末端脲上的甲基与末端烯烃的直接烷基化反应,得到相应加成产物的高产率。羟基铱/双膦配合物通过与具有NH键的脲反应生成酰胺基铱中间体。
